Specification forming part of Letters Patent No. 36,854, dated November 4, 1862.

To all whom it may concern.-

Be it known that I, J OSEPE RECKENDORFER, of New York,'in the county and State of New York, have invented a certain new and IlD-.

proved Pencil, whereof the following is a full and exact description, which I have prepared for the purpose of obtaining Letters Patent therefor. P i Y .,My' invention relates to wood-incased pen-- the wood and without making the pencil cumbrous or inconvenient.

In the drawings, Figure 1 is a side view; Fig; 2, a longitudinal-section; Fig. 3, acrosssectionon the line S S, and Fig. 4 a cross-section on the line Z Z;

'A. is the wood casing of the pencil, made in two parts and glued together in theordinary manner, --but made larger at one end than at,

the other, as represented; --This casing is grooved out with a small groove forthe reof the black-lead or plumbago B, as usual, but for only a portionof its length; The remainderat the larger end has a much larger groove, which is filled for nearly or quite itswhfole extent with indie-rubber G, as represented.

Pencils of equal size throughout havelbeen heretofora made with a slip of rubber fitted in, n place of the lead at one end, but such pencils have not become of any considerable practical importance,in consequence of the smallness of the rubber, and it has been held impractica- -ble to make the rubber much. larger without 1 too much weakening the wood or making the entire pencilthick and awkward to handle.

to. be larger than is necessary for lead to be without too much weakening -By myinvention: thesize of the rubber-may be so increased while that of'the lead remains the same,as to render it avery convenient and effective eraser. a

In preparingthe woodportions of my pencilsI first saw the material into tapering slips lying alternately with theends in opposite di-J ,rections',' aud afterward reduce these pieces to' the required form, thus economizi-ng material as far as possible.

I make the exterior of my improv ed pencil of a round, square, hexagonal, octagonahoval, or other section, as may bedesired, and finish it in any style, but always make-the end which contains the rubber of a larger diameter than the oppositeend and tapering gradually, Thelead and rubber may also be of any desired section, and may be also tapered,if preferred; but the rubber should always bev the larger,and I prefer the uniform section of each, as represented.

Anyother erasive. material may be substi;

tut-ed for the rubber O,-wi"tho'ut affecting the character of my invention-,jflora crayon or lead of a different color ,or'quality may be f substituted therefor, if desired. -Grayons and the soft-er qualities of lead require a larger section than thatgiven tothe part B, and the tapering'form of the casing'Apossesses the same advantages for their employment in combination with the lead B as for the rubber. I do not claim the combination of india-rubher and black-iead in the sai'ne wood-case; but What Ido claim as my'invention, and desire to-secur'e by'Letters Patent, is+

The wooden caseA oftapering form, in cornbination with the rubber G of largerse'ction, and the black-leadBof smaller section anranged'therein, substantiallyas'and for the purpose herein described.
